Dear Taweesak,
We have reviewed the drawings you sent back to us and have now realised the unit specified by us is incorrect and will not meet the duty.
The unit required is still an 8fan unit with equivalent length.
However the cross section of the unit should match a 10, 12 &14 fan units and include a coil with 80 Face tubes (80”).
Your recent drawing show 72 Face tubes
A general parameter layout is shown below.
We apologies for the change in information by us.
However BACA request you resubmit your quotation and revised drawings to meet the above information
